CIVIL AVIATION ACT 1988
CIVIL AVIATION SAFETY REGULATIONS 1998
ISSUE OF AIRWORTHINESS DIRECTIVE
Under section 98 of the Civil Aviation Act 1988, the Governor-General may make regulations for the purposes of the Act and in the interests of the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, CASA may issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. Subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998 provides that an AD is a disallowable instrument for the purposes of section 46A of the Acts Interpretation Act 1901. Therefore, in accordance with section 6 of the Legislative Instruments Act 2003, an AD is a legislative instrument.
Under Annex 8 to the Convention on International Civil Aviation, the State of Design has overall responsibility for continuing airworthiness of an aircraft type, and must provide any information necessary to ensure the continuing airworthiness of a type to appropriate States of Registry. ADs (and their equivalents) are the most common form of continuing airworthiness information, and are issued by most ICAO Contracting States.
The State of Registry of an individual aircraft is responsible for its continuing airworthiness. Under Annex 8, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft. When a State of Design issues an AD against a type of aircraft on the Australian Register, CASA, as Australia’s national airworthiness authority, must assess that information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design.
CASA issued AD/RYAN/2, affecting Ryan ST model aircraft in 1972. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 17 January 2008. No replacement AD is required, as the original unsafe condition is now addressed by AD/GENERAL/74 Amendment 1.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to regulate civil aviation in Australia and to ensure the safety of air navigation. Under the authority granted by section 98 of this Act, the Governor-General has the power to make regulations that serve the interests of air navigation safety. Complementing this, the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments subject to disallowance under section 46A of the Acts Interpretation Act 1901 and are regulated by the Legislative Instruments Act 2003. The objective of these regulations is to maintain the continuing airworthiness of aircraft, in line with international standards set by the Convention on International Civil Aviation, specifically Annex 8. This involves the State of Design issuing ADs, which the State of Registry, in this case CASA, must assess and implement as necessary to ensure compliance with airworthiness standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 98 of the Civil Aviation Act 1988, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products to ensure safety in air navigation. These ADs apply to the State of Registry of an aircraft and are necessary for maintaining the continuing airworthiness of aircraft types. The authority to issue such directives is derived from Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design responsibility for providing necessary information to ensure airworthiness. CASA, as Australia’s national airworthiness authority, must assess information from the State of Design and may issue Australian ADs if deemed necessary. For example, CASA issued and subsequently decided to cancel AD/RYAN/2, which affected Ryan ST model aircraft from 1972, effective from 17 January 2008. The cancellation did not require public consultation or a Regulatory Impact Statement, as it resulted in a reduction of regulatory burden, and no replacement AD was needed as the unsafe condition was addressed by another directive. This legislative instrument is a disallowable instrument under the Acts Interpretation Act 1901 and is considered a legislative instrument under the Legislative Instruments Act 2003.
Key Provisions
The Civil Aviation Act 1988, through section 98, allows the Governor-General to create regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs are designed to maintain the airworthiness of aircraft and are considered legislative instruments under subregulation 39.001(5) and section 6 of the Legislative Instruments Act 2003. The State of Design, which is responsible for the continuing airworthiness of an aircraft type, must provide necessary information to ensure safety, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Registry, which is responsible for the individual aircraft's continuing airworthiness, must then implement or adopt requirements to ensure the aircraft's safety. When a State of Design issues an AD for a type of aircraft registered in Australia, CASA must review this information and, if necessary, issue an Australian AD to enforce the requirements set by the State of Design.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are significant. The State of Design must ensure that all necessary information is provided to the State of Registry to maintain the continuing airworthiness of aircraft types. The State of Registry, in turn, must develop or adopt requirements to enforce these safety measures. CASA, as Australia's national airworthiness authority, is responsible for assessing ADs issued by the State of Design and, if appropriate, issuing Australian ADs to mandate these requirements. This process ensures that all aircraft registered in Australia meet the necessary safety standards. CASA's role includes reviewing and, if necessary, cancelling ADs when the conditions that necessitated them are no longer applicable, as was the case with AD/RYAN/2 for Ryan ST model aircraft, which was cancelled and deemed unnecessary due to the implementation of AD/GENERAL/74 Amendment 1.
The Civil Aviation Safety Regulations 1998, along with the Civil Aviation Act 1988, also outline the consequences of non-compliance with ADs. While the specific offences and penalties are not detailed in the provided text, it is clear that failure to adhere to ADs could result in significant civil or criminal consequences. Such non-compliance could potentially endanger the safety of air navigation, leading to severe penalties. Although the exact penalties are not specified in this excerpt, they could include fines, imprisonment, or other regulatory sanctions. The legal framework is designed to enforce strict adherence to airworthiness directives to prevent any compromise in the safety of aircraft operating within Australia.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a comprehensive regulatory framework aimed at ensuring the safety of air navigation. They mandate that the State of Design provides necessary information to the State of Registry, which must then implement requirements to maintain the airworthiness of aircraft. CASA plays a critical role in reviewing and enforcing these requirements through the issuance of airworthiness directives. Failure to comply with these directives could result in significant civil or criminal penalties, underscoring the importance of adhering to these safety regulations.
